There is a term I developed for Musou games 'need a body'. Basically it's when you just need someone else on the field/board. They don't have to do too much or anything like that, but it's a big boon to have someone who can do something minor like pull an important lever, kill off some of the chaff, and so-forth.

I suspect that, if I became a leader, my followers would be gunning for those situations. Not combat (of necessity) but where you just... need a body.
